Convert Android.mk to Android.bp

This commit converts Android.mk, android-config.mk, Scrypt.mk, and
Scrypt-config.mk files to an Android.bp file.

If BOARD_VNDK_VERSION is set to current, vendor modules won't be allowed
to link libscrypt_static.  To make libscrypt_static available to vendor
modules, we have to set vendor_available to true.  However,
vendor_available is an Android.bp feature, thus we have to convert
Android.mk to Android.bp first.
